Profile Gages   Thread Profile Print This Data Sheet TP Series How To Order Select the rod style standard model based on the size and type of connectors being measured. The TP Series of Thread Profile Gages are manufactured to tolerances of +.0002”, using EDM technology. These precision gages are ideal for quickly identifying each of the different thread forms named in the API Std. 5B and Specification 7. Profile gages can also be used to perform a visual inspection of a thread form for detecting chipped inserts, stretched threads, wide first threads, or rolled over threads. Special profiles are available and quoted upon request. TP-Series Thread Profile Gages Model No. TPF/TPI Thread Form Connector Type P-415 1.5" TPF, 4 TPI V-0.076 2 3/8"-3 1/2" P.A.C.
